Section 1 SWPPP Requirements
1.1 INTRODUCTION
The Palm Springs International Airport proposes to rehabilitate 34.4 acres of existing pavement.
The rehabilitation project will take place adjacent to the Bono Concourse in the Terminal Apron
area. Taxiway G is also included in the rehabilitation project. The entire project will occur within
the airport property. The projects location is shown on the Vicinity Map in Appendix B
This Stormwater Pollution Prevention Plan (SWPPP) is designed to comply with California’s
General Permit for Stormwater Discharges Associated with Construction and Land Disturbance
Activities (General Permit) Order No. 2009-0009-DWQ as amended by Order No.
2010-0014-DWQ (NPDES No. CAS000002) issued by the State Water Resources Control Board
(State Water Board). This SWPPP was prepared to compliment the Industrial Permit SWPPP
(733I001282) currently being implemented that was updated January 31, 2011 and all BMPs
described in this SWPPP are in addition to those outlined in the Industrial Permit SWPPP. This
SWPPP has been prepared following the SWPPP Template provided on the California
Stormwater Quality Association Stormwater Best Management Practice Handbook Portal:
Construction (CASQA, 2010). In accordance with the General Permit, Section XIV, this
SWPPP is designed to address the following:
x Pollutants and their sources, including sources of sediment associated with construction,
construction site erosion and other activities associated with construction activity are
controlled;
x Where not otherwise required to be under a Regional Water Quality Control Board
(Regional Water Board) permit, all non-stormwater discharges are identified and either
eliminated, controlled, or treated;
x Site BMPs are effective and result in the reduction or elimination of pollutants in
stormwater discharges and authorized non-stormwater discharges from construction
activity to the Best Available Technology/Best Control Technology (BAT/BCT)
standard;
Calculations and design details as well as BMP controls are complete and correct, and are in
Appendix A.
This is a Risk Level 1 project and therefore will not require Rain Event Action Plans (REAP’s).
1.2 PERMIT REGISTRATION DOCUMENTS
Required Permit Registration Documents (PRDs) shall be submitted to the State Water Board via
the Stormwater Multi Application and Report Tracking System (SMARTS) by the Legally
Responsible Person (LRP), or authorized personnel (i.e., Approved Signatory) under the
direction of the LRP. The project-specific PRDs include:
1. Notice of Intent (NOI);
2. Risk Assessment (Construction Site Sediment and Receiving Water Risk Determination);
3. Site Map;

CASQA SWPPP Template 9 January 2011
1.7 ANNUAL REPORT
The General Permit requires that permittees prepare, certify, and electronically submit an Annual
Report no later than September 1st of each year. Reporting requirements are identified in Section
XVI of the General Permit. Annual reports will be filed in SMARTS and in accordance with
information required by the on-line forms.
1.8 CHANGES TO PERMIT COVERAGE
The General Permit allows for the reduction or increase of the total acreage covered under the
General Permit when: a portion of the project is complete and/or conditions for termination of
coverage have been met; when ownership of a portion of the project is purchased by a different
entity; or when new acreage is added to the project.
Modified PRDs shall be filed electronically within 30 days of a reduction or increase in total
disturbed area if a change in permit covered acreage is to be sought. The SWPPP shall be
modified appropriately, shall be logged at the front of the SWPPP and certification of SWPPP
amendments are to be kept in Appendix D. Updated PRDs submitted electronically via SMARTS
can be found in Appendix E.

terminate coverage under the General Permit. The NOT must include a final Site Map and
representative photographs of the project site that demonstrate final stabilization has been
achieved. The NOT shall be submitted within 90 days of completion of construction. The
Regional Water Board will consider a construction site complete when the conditions of the
General Permit, Section II.D have been met.
CASQA SWPPP Template 10 January 2011
Section 2 Project Information
2.1 PROJECT AND SITE DESCRIPTION
2.1.1 Site Description
The Palm Springs International Airport is located south of Interstate 10 in the City of Palm
Springs, Riverside County, California. The airport covers 940 acres of land. The terminal apron
area is southwest of the runways and surrounds the main terminal and adjoining concrete slab.
Taxiway G is located northwest of the main terminal and the air traffic control tower. Palm
Springs International Airport is a commercial aviation airport with one existing commercial
runway and one existing general aviation runway.
The airport lies within the greater Whitewater River Watershed. Runoff from the airport drains to
a regional master planned retention basin with 43 acre feet of storage located at the southeastern
corner of the airport. A 24 inch storm drain outlet conveys flows from the basin east to the
Whitewater River where flows are directed south via stream flow to the Salton Sea.
2.1.2 Existing Conditions
As of the initial date of this SWPPP, the project site is comprised of a mixture of impervious
surfaces that include concrete and asphalt pavements. The terminal apron area consists of
asphalt pavement on aggregate base, while Taxiway G consists of asphalt pavement on alluvial
soil.
According to Geotracker, there are no historic sources of contamination within the project area.
However several historic storage tank facilities along El Cielo Road and North Civic Drive were
identified but are not considered a potential source of contamination for construction related
activities due to all clean up statuses being complete and all cases closed.
2.1.3 Existing Drainage
Onsite surface drainage consists primarily of sheet flow and shallow concentrated flow across
the Terminal Apron. Typical drainage patterns are from north to south. Drainage through the
terminal apron is conveyed as surface drainage. Existing storm drain inlets located intermittently
throughout the area intercept surface runoff and convey flows through a oil/water separator prior
to discharging to the Regional Retention Basin. The retention basin is identified in the Palm
Springs Master Plan of Drainage and is in place to reduce the amount of flow released from the
site. Taxiway G drainage is characterized by sheet flow that drains off the pavement to an
adjacent channel that flows east downstream where the flows confluence with the Terminal.
As previously mentioned the project discharges to the Whitewater River Wash. The Whitewater
River is not identified on the 303 d list as impaired. However the Whitewater River transitions
into the Coachella Valley Storm Water Channel that is 303 disted for the following constituents.
x DDT
x Dieldren
x PCBs
CASQA SWPPP Template 11 January 2011
x Pathogens
x Toxaphene
2.1.4 Geology and Groundwater
The site is underlain by artificial fill and alluvium. Locally the soils encountered consisted of
poorly graded sands with silt and silty sands with traces of gravel. The artificial fill soils
encountered consisted of asphalt and aggregate base. The asphalt ranged from 4 to 12 inches in
thickness and the aggregate base ranged from 3 to 8 inches in thickness. In general, the asphalt
encountered in the apron area appeared to be fair to poor condition with low to medium severity
alligator, block and longitudinal cracking, cracking along utility trenches, rutting, erosions,
exposed aggregate and raveling and weathering. The asphalt encountered at Taxiway G was
generally in poor condition with moderate to severe alligator and block cracking, rutting and
weathering. The alluvial soils encountered during field investigations were relatively course
grained and were classified as SM and SP-SM in accordance with the Unified Soils
Classification System. These soils are not corrosive to metals, have negligible amounts of
sulfates and are non expansive in nature. In general, the upper 3 to 5 feet of the alluvial soils
around the terminal apron are dense to very dense. The near surface soils beneath Taxiway G
were generally medium dense. According to Websoil Survey soils in the area soils consists of
Myoma fine sand.
During Geotechnical investigations no springs or areas of natural seepage were found and no
groundwater was encountered during subsurface exploration. According to California
Department of Water Resources groundwater in the vicinity varies from 170 feet below mean sea
level to 195 below mean sea level.
2.1.5 Project Description
The rehabilitation and reconstruction project will remove and replace the terminal apron and
resurface Taxiway G that will total 34.4 acres. The rehabilitation project is necessary due to the
degradation that has occurred to the pavement over the last 30 years. The removal and
replacement will consists of several steps. Initially, the existing pavement will be removed,
grinded and stockpiled. The substrate below the existing pavement will be tested for bearing
capacity and will be removed and recompacted as necessary to meet the required bearing
capacity. Depth of excavation is not planned to extend below four feet. There will be no increase
to impervious surfaces and the majority of the pavement area will be replaced or resurfaced at
existing grade
The limits of grading are shown in Appendix B. Preliminary earthwork calculations have
demonstrated the project will require net export of soil but exact quantities have yet to be
determined. Construction activities will be phased to accommodate airport operations as
necessary.
2.1.6 Developed Condition
Post construction surface drainage will be managed in the same manner as in the existing
condition. Existing hydraulic capacity and grade will maintained in the developed condition. The
existing storm drain systems will be utilized in the developed condition. Existing impervious
coverage will be maintained in the proposed condition and no new impervious surfaces will be
CASQA SWPPP Template 12 January 2011
introduced. Existing drainage infrastructure that includes the inlets, stormdrain, oil water
separator and retention basin will be maintained in the developed condition. Post construction
drainage boundaries will match existing.
Drainage boundaries and conveyance systems are presented in Appendix B.

2.2 PERMITS AND GOVERNING DOCUMENTS
In addition to the General Permit, the following documents have been taken into account while
preparing this SWPPP
x Regional Water Board requirements
x Basin Plan requirements
x Contract Documents
x Air Quality Regulations and Permits
2.3 STORMWATER RUN-ON FROM OFFSITE AREAS
There is no existing offsite run-on to this construction site.
2.4 FINDINGS OF THE CONSTRUCTION SITE SEDIMENT AND
RECEIVING WATER RISK DETERMINATION
A construction site risk assessment has been performed for the project and the resultant risk level
is Risk Level 1.
The risk level was determined through the use of the spreadsheet provided by the State Water
resources Control Board that accounts for sediment risk and receiving water risk to predict the
Risk Level. The sediment risk was determined based on R, K, and LS as defined by the
Universal Soil Loss Equation. The R factor was calculated by using Fact Sheet 3.1 provided by
the Environmental Protection Agency (EPA). The K factor was determined based on information
provided by Websoil Survey. The LS factor was determined based on the average slope through
the site (2%) and set to the maximum sheet flow length of 1000 feet. The risk level is based on
CASQA SWPPP Template 13 January 2011
project duration, location, proximity to impaired receiving waters and soil conditions. A copy of
the Risk Level determination submitted on SMARTS with the PRDs is included in Appendix C.
Table 2.2 and Table 2.3 summarize the sediment and receiving water risk factors and document
the sources of information used to derive the factors.

Risk Level 1 sites are subject to narrative effluent limitations but are not subject to the numeric
effluent standards. The narrative effluent limitations require stormwater discharges associated
with construction activity to minimize or prevent pollutants in stormwater and authorized non-
stormwater through the use of controls, structures and best management practices. Discharges
shall not contain hazardous substances equal to or in excess of reportable quantities established
in 40 CFR 117.3 and 302.4. This SWPPP has been prepared to address Risk Level 1
requirements (General Permit Attachment D).
2.5 CONSTRUCTION SCHEDULE
The site sediment risk was determined based on construction taking place between June 1, 2013
and September 30, 2014. The construction schedule will be divided into six phases that will
CASQA SWPPP Template 14 January 2011
allow for airport operations to continue throughout construction. This schedule will also help to
limit the amount of disturbed soil area exposed at any one time. Modification or extension of the
schedule (start and end dates) may affect risk determination and permit requirements. The LRP
shall contact the QSD if the schedule changes during construction to address potential impact to
the SWPPP. The estimated schedule for planned work can be found in Appendix F.
2.6 POTENTIAL CONSTRUCTION ACTIVITY AND POLLUTANT SOURCES
Appendix G includes a list of construction activities and associated materials that are anticipated
to be used onsite. These activities and associated materials will or could potentially contribute
pollutants, other than sediment, to stormwater runoff.
The anticipated activities and associated pollutants were used in Section 3 to select the Best
Management Practices for the project. Location of anticipated pollutants and associated BMPs
are shown in Appendix B.
For sampling requirements for non-visible pollutants associated with construction activity please
refer to Section 7.7.1. For a full and complete list of onsite pollutants, refer to the Material
Safety Data Sheets (MSDS), which should be retained onsite at the construction trailer.
2.7 IDENTIFICATION OF NON-STORMWATER DISCHARGES
Non-stormwater discharges consist of discharges which do not originate from precipitation
events. The General Permit provides allowances for specified non-stormwater discharges that do
not cause erosion or carry other pollutants.
Non-stormwater discharges into storm drainage systems or waterways, which are not authorized
under the General Permit and listed in the SWPPP, or authorized under a separate NPDES
permit, are prohibited.
Non-stormwater discharges that are authorized from this project site include the following:
x Wind Erosion Control
These authorized non-stormwater discharges will be managed with the stormwater and non-
stormwater BMPs described in Section 3 of this SWPPP and will be minimized by the QSP.
Activities at this site that may result in unauthorized non-stormwater discharges include:
x Dewatering
x High Pressure Water Blasting
It is recommended to allow any standing water after storm events to infiltrate as opposed to
pumping the water downstream. In the event that pumping water is necessary the QSP will verify
they have the proper permit and will ensure any pumped water is free of sediment. Steps will be
taken, including the implementation of appropriate BMPs, to ensure that unauthorized discharges
are eliminated, controlled, disposed, or treated on-site.
Discharges of construction materials and wastes, such as fuel or paint, resulting from dumping,
spills, or direct contact with rainwater or stormwater runoff, are also prohibited.

3.2 EROSION AND SEDIMENT CONTROL
Erosion and sediment controls are required by the General Permit to provide effective reduction
or elimination of sediment related pollutants in stormwater discharges and authorized non-
stormwater discharges from the Site. Applicable BMPs are identified in this section for erosion
control, sediment control, tracking control, and wind erosion control.
3.2.1 Erosion Control
Erosion control, also referred to as soil stabilization, consists of source control measures that are
designed to prevent soil particles from detaching and becoming transported in stormwater
runoff. Erosion control BMPs protect the soil surface by covering and/or binding soil particles.
This construction project will implement the following practices to provide effective temporary
and final erosion control during construction:
1. The area of soil disturbing operations shall be controlled such that the Contractor is able
to implement erosion control BMPs quickly and effectively.
2. Stabilize non-active areas within 14 days of cessation of construction activities or sooner
if stipulated by local requirements.
3. Control erosion in concentrated flow paths by applying erosion control blankets, check
dams, erosion control seeding or alternate methods.
Sufficient erosion control materials shall be maintained onsite to allow implementation in
conformance with this SWPPP.
The following temporary erosion control BMP selection table indicates the BMPs that shall be
implemented to control erosion on the construction site. Fact Sheets for temporary erosion
control BMPs are provided in Appendix H.

Scheduling
Special consideration will be given to land disturbing activities as to minimize the amount of
exposed disturbed soil at any one time. The project will be broken up into six phases in order to
minimize the exposed disturbed soil area.
Geotextiles and Mats
Geotextiles will be anchored with gravel bags over storm drain inlets to reduce the potential for
sediment to enter storm drains.
Earth Dike and Drainage Swales
A concentrated flow path exist down the middle of Taxiway G. The drainage swale will be
managed with gravel bags or equivalent as determined by the contractor before likely rain events
when in a disturbed state to ensure cutting from erosive flows is minimized and sediment
transport downstream is controlled.

Fiber Rolls
Fiber rolls will be placed intermittently throughout the project to intercept runoff, reduce its flow
velocity, reduce the runoff as sheetflow and therefore reduce the potential for sheet and rill
erosion.
Gravel Bag Berm
Gravel bags will be used throughout the site to pond sheet flow runoff and allow sediment to
settle out. During each phase of construction gravel bags should be placed on the upstream side
of the disturbed area boundary to intercept sheet flow and redirect the runoff around the
disturbed area.
Street Sweeping
Street sweeping for the areas around Palm Springs Airport are scheduled for the 1st Friday, 2nd
Wednesday, and 3rd Tuesday of every month .Street sweeping will be performed onsite as
necessary to remove accumulated sediment and debris.
Storm Drain Inlet Protection

ingress/egress will be constructed with rattle plates and large diameter gravel to allow sediment
to be dislodged from trucks prior to leaving the site. Any accumulated sediment will be removed
immediately.
3.3 NON-STORMWATER CONTROLS AND WASTE AND MATERIALS
MANAGEMENT
3.3.1 Non-Stormwater Controls
Non-stormwater discharges into storm drainage systems or waterways, which are not authorized
under the General Permit, are prohibited. Non-stormwater discharges for which a separate
NPDES permit is required by the local Regional Water Board are prohibited unless coverage
under the separate NPDES permit has been obtained for the discharge. The selection of non-
stormwater BMPs is based on the list of construction activities with a potential for non-
stormwater discharges identified in Section 2.7 of this SWPPP.

the Fact Sheet. The narrative in the body of the SWPPP prevails over guidance in the BMP Fact
Sheets.
Water Conservation Practices
All activities that involve the use of water including line flushing and wind erosion control
practices should be performed in a manner that avoids causing erosion and the transport of
pollutants offsite. The goal of water conservation practices is to reduce or eliminate non-
stormwater discharges.
Dewatering Operation
If accumulated precipitation will cause a significant impact to construction operations there is the
potential that dewatering maybe necessary. Any dewatering activities should ensure that water is
filtered or otherwise treated for sediment prior to discharge. All effluent is subject to sampling if
there is the potential for contaminants to be discharged.
Paving and Grinding Operation
Paving and grinding activities should entail shoveling or vacuuming saw-cut slurry and removal
from site. During AC paving the proper steps should be taken to prevent the discharge of
grinding residue, uncompacted or loose AC, tack coats, equipment cleaners, or unrelated paving
materials.
Illicit Connection- Illegal Discharge Connection
Any illicit connections or illegal discharges will be reported to the County Stormwater Hotline at
1-800-506-2555.
Vehicle and Equipment Cleaning
Cleaning of equipment and vehicles should consider the following: using offsite facilities,
washing in designated contained areas only, and eliminating discharges to the storm drain by
infiltrating wash water.
Vehicle and Equipment Fueling
Fueling activities should consider the following: using offsite facilities, fueling in designated
areas only, enclosing or covering stored fuel, implementing spill controls, and training
employees and subcontractors in proper fueling procedures.
Vehicle and Equipment Maintenance
Vehicle and equipment maintenance should be performed in designated areas only, while
providing cover for materials stored outside, checking for leaks and spills, and containing and
cleaning up spills immediately.
Concrete Curing
Concrete curing should be performed in a manner as to avoid over spraying of curing
compounds, minimizing drift by applying close to concrete surface, protecting drain inlets prior
to application and using proper storage for compound.
CASQA SWPPP Template 24 January 2011
Concrete Finishing
Concrete finishing activities should include directing water from blasting away from inlets to
collection areas for infiltration or other means of removal, minimizing the drift of dust and blast
material by kepping the nozzle close to the surface, disposing of residue as a hazardous waste.
High Pressure Water Blasting
High pressure water blasting will be performed to remove striping from pavement. A vacuum
will follow the high pressure sprayer to remove the spray waste immediately and ensure waste
water does not provide a source of non stormwater discharges from the construction site.
3.3.2 Materials Management and Waste Management
Materials management control practices consist of implementing procedural and structural BMPs
for handling, storing and using construction materials to prevent the release of those materials
into stormwater discharges. The amount and type of construction materials to be utilized at the
Site will depend upon the type of construction and the length of the construction period. The
materials may be used continuously, such as fuel for vehicles and equipment, or the materials
may be used for a discrete period, such as soil binders for temporary stabilization.
Waste management consist of implementing procedural and structural BMPs for handling,
storing and ensuring proper disposal of wastes to prevent the release of those wastes into
stormwater discharges. If applicable to the project site, waste management should be conducted
in accordance with the Project’s Construction Waste Management Plan.
Materials and waste management pollution control BMPs shall be implemented to minimize
stormwater contact with construction materials, wastes and service areas; and to prevent
materials and wastes from being discharged off-site. The primary mechanisms for stormwater
contact that shall be addressed include:
x Direct contact with precipitation
x Contact with stormwater run-on and runoff
x Wind dispersion of loose materials
x Direct discharge to the storm drain system through spills or dumping
x Extended contact with some materials and wastes, such as asphalt cold mix and treated
wood products, which can leach pollutants into stormwater.
A list of construction activities is provided in Section 2.6. The following Materials and Waste
Management BMP selection table indicates the BMPs that shall be implemented to handle
materials and control construction site wastes associated with these construction activities. Fact
Sheets for Materials and Waste Management BMPs are provided in Appendix H.

Section 7 Construction Site Monitoring Program
7.1 Purpose
This Construction Site Monitoring Program was developed to address the following objectives:
1. To demonstrate that the site is in compliance with the Construction General Permit;
2. To determine whether non-visible pollutants are present at the construction site and are
causing or contributing to exceedances of water quality objectives;
3. To determine whether immediate corrective actions, additional Best Management
Practices (BMP) implementation, or SWPPP revisions are necessary to reduce pollutants
in stormwater discharges and authorized non-stormwater discharges;
4. To determine whether BMPs included in the SWPPP are effective in preventing or
reducing pollutants in stormwater discharges and authorized non-stormwater discharges.
7.2 Applicability of Permit Requirements
This project has been determined to be a Risk Level 1 project. The General Permit identifies the
following types of monitoring as being applicable for Risk Level 1 projects.

7.7 Water Quality Sampling and Analysis
7.7.1 Sampling and Analysis Plan for Non-Visible Pollutants in Stormwater Runoff
Discharges
This Sampling and Analysis Plan for Non-Visible Pollutants describes the sampling and analysis
strategy and schedule for monitoring non-visible pollutants in stormwater runoff discharges from
the project site.
Sampling for non-visible pollutants will be conducted when (1) a breach, leakage, malfunction,
or spill is observed; and (2) the leak or spill has not been cleaned up prior to the rain event; and
(3) there is the potential for discharge of non-visible pollutants to surface waters or drainage
system.
CASQA SWPPP Template 38 January 2011
The following construction materials, wastes, or activities, as identified in the Table below, are
potential sources of non-visible pollutants to stormwater discharges from the project.
7.7.1.1 Sampling Schedule
Samples for the potential non-visible pollutant(s) and a sufficiently large unaffected background
sample shall be collected during the first two hours of discharge from rain events that result in a
sufficient discharge for sample collection. Samples shall be collected during the site’s scheduled
hours and shall be collected regardless of the time of year and phase of the construction.
Collection of discharge samples for non-visible pollutant monitoring will be triggered when any
of the following conditions are observed during site inspections conducted prior to or during a
rain event.
x Materials or wastes containing potential non-visible pollutants are not stored under
watertight conditions. Watertight conditions are defined as (1) storage in a watertight
container, (2) storage under a watertight roof or within a building, or (3) protected by
temporary cover and containment that prevents stormwater contact and runoff from the
storage area.
CASQA SWPPP Template 39 January 2011
x Materials or wastes containing potential non-visible pollutants are stored under watertight
conditions, but (1) a breach, malfunction, leakage, or spill is observed, (2) the leak or
spill is not cleaned up prior to the rain event, and (3) there is the potential for discharge of
non-visible pollutants to surface waters or a storm drain system.
x A construction activity with the potential to contribute non-visible pollutants (1) was
occurring during or within 24 hours prior to the rain event, (2) BMPs were observed to be
breached, malfunctioning, or improperly implemented, and (3) there is the potential for
discharge of non-visible pollutants to surface waters or a storm drain system.
x Soil amendments that have the potential to change the chemical properties, engineering
properties, or erosion resistance of the soil have been applied, and there is the potential
for discharge of non-visible pollutants to surface waters or a storm drain system.
x Stormwater runoff from an area contaminated by historical usage of the site has been
observed to combine with stormwater runoff from the site, and there is the potential for
discharge of non-visible pollutants to surface waters or a storm drain system.
7.7.1.2 Sampling Locations
Sampling locations should be based on proximity to planned non-visible pollutant storage,
occurrence or use; accessibility for sampling, and personnel safety.
If a stormwater visual monitoring site inspection conducted prior to or during a storm event
identifies the presence of a material storage, waste storage, or operations area with spills or the
potential for the discharge of non-visible pollutants to surface waters or a storm drain system that
is at a location not listed above and has not been identified on the Site Maps, sampling locations
will be selected by the QSP using the same rationale as that used to identify planned locations.
Non-visible pollutant sampling locations shall be identified by the QSP on the pre-rain event
inspection form prior to a forecasted qualifying rain event.

Name Training
The stormwater sampler(s) and alternates have the following stormwater sampling experience:
Name Experience
7.7.7 Sample Collection and Handling
7.7.7.1 Sample Collection
Samples shall be collected at the designated sampling locations shown on the Site Maps and
listed in the preceding sections. Samples shall be collected, maintained and shipped in
accordance with the SWAMP 2008 Quality Assurance Program Plan (QAPrP).
Grab samples shall be collected and preserved in accordance with the methods identified in
preceding sections.
To maintain sample integrity and prevent cross-contamination, sample collection personnel shall
follow the protocols below.
x Collect samples (for laboratory analysis) only in analytical laboratory-provided sample
containers;
x Wear clean, powder-free nitrile gloves when collecting samples;
x Change gloves whenever something not known to be clean has been touched;
x Change gloves between sites;
x Decontaminate all equipment (e.g. bucket, tubing) prior to sample collection using a
trisodium phosphate water wash, distilled water rinse, and final rinse with distilled water.
(Dispose of wash and rinse water appropriately, i.e., do not discharge to storm drain or
receiving water). Do not decontaminate laboratory provided sample containers;
x Do not smoke during sampling events;
CASQA SWPPP Template 49 January 2011
x Never sample near a running vehicle;
x Do not park vehicles in the immediate sample collection area (even non-running
vehicles);
x Do not eat or drink during sample collection; and
x Do not breathe, sneeze, or cough in the direction of an open sample container.
The most important aspect of grab sampling is to collect a sample that represents the entire
runoff stream. Typically, samples are collected by dipping the collection container in the runoff
flow paths and streams as noted below.
i. For small streams and flow paths, simply dip the bottle facing upstream until full.
ii. For larger stream that can be safely accessed, collect a sample in the middle of the flow
stream by directly dipping the mouth of the bottle. Once again making sure that the
opening of the bottle is facing upstream as to avoid any contamination by the sampler.
iii. For larger streams that cannot be safely waded, pole-samplers may be needed to safely
access the representative flow.
iv. Avoid collecting samples from ponded, sluggish or stagnant water.
v. Avoid collecting samples directly downstream from a bridge as the samples can be
affected by the bridge structure or runoff from the road surface.
Note, that depending upon the specific analytical test, some containers may contain
preservatives. These containers should never be dipped into the stream, but filled indirectly from
the collection container.
7.7.7.2 Sample Handling
Samples for laboratory analysis must be handled as follows. Immediately following sample
collection:
x Cap sample containers;
x Complete sample container labels;
x Sealed containers in a re-sealable storage bag;
x Place sample containers into an ice-chilled cooler;
x Document sample information on the Effluent Sampling Field Log Sheet; and
x Complete the CoC.
All samples for laboratory analysis must be maintained between 0-6 degrees Celsius during
delivery to the laboratory. Samples must be kept on ice, or refrigerated, from sample collection
through delivery to the laboratory. Place samples to be shipped inside coolers with ice. Make
sure the sample bottles are well packaged to prevent breakage and secure cooler lids with
packaging tape.
Ship samples that will be laboratory analyzed to the analytical laboratory right away. Hold times
are measured from the time the sample is collected to the time the sample is analyzed. The
General Permit requires that samples be received by the analytical laboratory within 48 hours of
the physical sampling (unless required sooner by the analytical laboratory).

7.7.7.3 Sample Documentation Procedures
All original data documented on sample bottle identification labels, Effluent Sampling Field Log
Sheet, and CoCs shall be recorded using waterproof ink. These shall be considered accountable
documents. If an error is made on an accountable document, the individual shall make
corrections by lining through the error and entering the correct information. The erroneous
information shall not be obliterated. All corrections shall be initialed and dated.
Duplicate samples shall be identified consistent with the numbering system for other samples to
prevent the laboratory from identifying duplicate samples. Duplicate samples shall be identified
in the Effluent Sampling Field Log Sheet.
Sample documentation procedures include the following:
Sample Bottle Identification Labels: Sampling personnel shall attach an identification label to
each sample bottle. Sample identification shall uniquely identify each sample location.
Field Log Sheets: Sampling personnel shall complete the Effluent Sampling Field Log Sheet and
Receiving Water Sampling Field Log Sheet for each sampling event, as appropriate.
Chain of Custody: Sampling personnel shall complete the CoC for each sampling event for
which samples are collected for laboratory analysis. The sampler will sign the CoC when the
sample(s) is turned over to the testing laboratory or courier.
7.8 Active Treatment System Monitoring
An Active Treatment System (ATS) will be deployed on the site?
Yes No
This project does not require a project specific Sampling and Analysis Plan for an ATS because
deployment of an ATS is not planned.
The project specific Sampling and Analysis Plan for the ATS is provided in the ATS Monitoring
and Sampling Plan (MSRP).
7.9 Bioassessment Monitoring
This project is not subject to bioassessment monitoring because it is not a Risk Level 3 project.
7.10 Watershed Monitoring Option
This project is not participating in a watershed monitoring option.
CASQA SWPPP Template 51 January 2011
7.11 Quality Assurance and Quality Control
An effective Quality Assurance and Quality Control (QA/QC) plan shall be implemented as part
of the CSMP to ensure that analytical data can be used with confidence. QA/QC procedures to
be initiated include the following:
x Field logs;
x Clean sampling techniques;
x CoCs;
x QA/QC Samples; and
x Data verification.
Each of these procedures is discussed in more detail in the following sections.
7.11.1 Field Logs
The purpose of field logs is to record sampling information and field observations during
monitoring that may explain any uncharacteristic analytical results. Sampling information to be
included in the field log include the date and time of water quality sample collection, sampling
personnel, sample container identification numbers, and types of samples that were collected.
Field observations should be noted in the field log for any abnormalities at the sampling location
(color, odor, BMPs, etc.). Field measurements for pH and turbidity should also be recorded in
the field log. A Visual Inspection Field Log, an Effluent Sampling Field Log Sheet, and a
Receiving Water Sampling Field Log Sheet are included in CSMP Attachment 3 “Example
Forms”.
7.11.2 Clean Sampling Techniques
Clean sampling techniques involve the use of certified clean containers for sample collection and
clean powder-free nitrile gloves during sample collection and handling. Adoption of a clean
sampling approach will minimize the chance of field contamination and questionable data
results.
7.11.3 Chain of Custody
The sample CoC is an important documentation step that tracks samples from collection through
analysis to ensure the validity of the sample. Sample CoC procedures include the following:
x Proper labeling of samples;
x Use of CoC forms for all samples; and
x Prompt sample delivery to the analytical laboratory.
Analytical laboratories usually provide CoC forms to be filled out for sample containers. An
example CoC is included in CSMP Attachment 3 “Example Forms”.
7.11.4 QA/QC Samples
QA/QC samples provide an indication of the accuracy and precision of the sample collection;
sample handling; field measurements; and analytical laboratory methods. The following types of
QA/QC will be conducted for this project:
CASQA SWPPP Template 52 January 2011
Field Duplicates at a frequency of 5 percent or 1 duplicate minimum per sampling event
(Required for all sampling plans with field measurements or laboratory analysis)
Equipment Blanks at a frequency of 1 duplicate minimum per sampling event
(Only needed if equipment used to collect samples could add the pollutants to sample)
Field Blanks at a frequency of 1 duplicate minimum per sampling event
(Only required if sampling method calls for field blanks)
Travel Blanks at a frequency of 1 duplicate minimum per sampling event
(Required for sampling plans that include VOC laboratory analysis)
7.11.4.1 Field Duplicates
Field duplicates provide verification of laboratory or field analysis and sample collection.
Duplicate samples shall be collected, handled, and analyzed using the same protocols as primary
samples. The sample location where field duplicates are collected shall be randomly selected
from the discharge locations. Duplicate samples shall be collected immediately after the primary
sample has been collected. Duplicate samples must be collected in the same manner and as close
in time as possible to the original sample. Duplicate samples shall not influence any evaluations
or conclusion.
7.11.4.2 Equipment Blanks
Equipment blanks provide verification that equipment has not introduced a pollutant into the
sample. Equipment blanks are typically collected when:
x New equipment is used;
x Equipment that has been cleaned after use at a contaminated site;
x Equipment that is not dedicated for surface water sampling is used; or
x Whenever a new lot of filters is used when sampling metals.
7.11.4.3 Field Blanks
Field blanks assess potential sample contamination levels that occur during field sampling
activities. De-ioninzed water field blanks are taken to the field, transferred to the appropriate
container, and treated the same as the corresponding sample type during the course of a sampling
event.
7.11.4.4 Travel Blanks
Travel blanks assess the potential for cross-contamination of volatile constituents between
sample containers during shipment from the field to the laboratory. De-ioninzed water blanks
are taken along for the trip and held unopened in the same cooler with the VOC samples.
7.11.5 Data Verification
After results are received from the analytical laboratory, the QSP shall verify the data to ensure
that it is complete, accurate, and the appropriate QA/QC requirements were met. Data must be
verified as soon as the data reports are received. Data verification shall include:
CASQA SWPPP Template 53 January 2011
x Check the CoC and laboratory reports.
Make sure all requested analyses were performed and all samples are accounted for in
the reports.
x Check laboratory reports to make sure hold times were met and that the reporting levels
meet or are lower than the reporting levels agreed to in the contract.
x Check data for outlier values and follow up with the laboratory.
Occasionally typographical errors, unit reporting errors, or incomplete results are
reported and should be easily detected. These errors need to be identified, clarified, and
corrected quickly by the laboratory. The QSP should especially note data that is an
order of magnitude or more different than similar locations, or is inconsistent with
previous data from the same location.
x Check laboratory QA/QC results.
EPA establishes QA/QC checks and acceptable criteria for laboratory analyses. These
data are typically reported along with the sample results. The QSP shall evaluate the
reported QA/QC data to check for contamination (method, field, and equipment blanks),
precision (laboratory matrix spike duplicates), and accuracy (matrix spikes and
laboratory control samples). When QA/QC checks are outside acceptable ranges, the
laboratory must flag the data, and usually provides an explanation of the potential
impact to the sample results.
x Check the data set for outlier values and, accordingly, confirm results and re-analyze
samples where appropriate.
Sample re-analysis should only be undertaken when it appears that some part of the
QA/QC resulted in a value out of the accepted range. Sample results may not be
discounted unless the analytical laboratory identifies the required QA/QC criteria were
not met and confirms this in writing.
Field data including inspections and observations must be verified as soon as the field logs are
received, typically at the end of the sampling event. Field data verification shall include:
x Check field logs to make sure all required measurements were completed and
appropriately documented;
x Check reported values that appear out of the typical range or inconsistent;
Follow-up immediately to identify potential reporting or equipment problems, if
appropriate, recalibrate equipment after sampling;
x Verify equipment calibrations;
x Review observations noted on the field logs; and
x Review notations of any errors and actions taken to correct the equipment or recording
errors.
7.12 Records Retention
All records of stormwater monitoring information and copies of reports (including Annual
Reports) must be retained for a period of at least three years from date of submittal or longer if
required by the Regional Water Board.
Results of visual monitoring, field measurements, and laboratory analyses must be kept in the
SWPPP along with CoCs, and other documentation related to the monitoring.
Records are to be kept onsite while construction is ongoing. Records to be retained include:
CASQA SWPPP Template 54 January 2011
x The date, place, and time of inspections, sampling, visual observations, and/or
measurements, including precipitation;
x The individual(s) who performed the inspections, sampling, visual observation, and/or
field measurements;
x The date and approximate time of field measurements and laboratory analyses;
x The individual(s) who performed the laboratory analyses;
x A summary of all analytical results, the method detection limits and reporting limits, and
the analytical techniques or methods used;
x Rain gauge readings from site inspections;
x QA/QC records and results;
x Calibration records;
x Visual observation and sample collection exemption records;
x The records of any corrective actions and follow-up activities that resulted from
analytical results, visual observations, or inspections;

Description
Erosion factor K indicates the susceptibility of a soil to sheet and rill erosion by
water. Factor K is one of six factors used in the Universal Soil Loss Equation (USLE)
and the Revised Universal Soil Loss Equation (RUSLE) to predict the average
annual rate of soil loss by sheet and rill erosion in tons per acre per year. The
estimates are based primarily on percentage of silt, sand, and organic matter and
on soil structure and saturated hydraulic conductivity (Ksat). Values of K range from
0.02 to 0.69. Other factors being equal, the higher the value, the more susceptible
the soil is to sheet and rill erosion by water.
"Erosion factor Kw (whole soil)" indicates the erodibility of the whole soil. The
estimates are modified by the presence of rock fragments.

Sediment Risk Factor Worksheet
A) R Factor
R Factor Value
B) K Factor (weighted average, by area, for all site soils)
Analyses of data indicated that when factors other than rainfall are held constant, soil loss is directly proportional to a
rainfall factor composed of total storm kinetic energy (E) times the maximum 30-min intensity (I30) (Wischmeier and
Smith, 1958). The numerical value of R is the average annual sum of EI30 for storm events during a rainfall record of
at least 22 years. "Isoerodent" maps were developed based on R values calculated for more than 1000 locations in
the Western U.S. Refer to the link below to determine the R factor for the project site.
http://cfpub.epa.gov/npdes/stormwater/LEW/lewCalculator.cfm
K Factor Value
LS Factor Value
Low
C) LS Factor (weighted average, by area, for all slopes)
The soil-erodibility factor K represents: (1) susceptibility of soil or surface material to erosion, (2) transportability of the
sediment, and (3) the amount and rate of runoff given a particular rainfall input, as measured under a standard
condition. Fine-textured soils that are high in clay have low K values (about 0.05 to 0.15) because the particles are
resistant to detachment. Coarse-textured soils, such as sandy soils, also have low K values (about 0.05 to 0.2)
because of high infiltration resulting in low runoff even though these particles are easily detached. Medium-textured
soils, such as a silt loam, have moderate K values (about 0.25 to 0.45) because they are moderately susceptible to
particle detachment and they produce runoff at moderate rates. Soils having a high silt content are especially
susceptible to erosion and have high K values, which can exceed 0.45 and can be as large as 0.65. Silt-size particles
are easily detached and tend to crust, producing high rates and large volumes of runoff. Use Site-specific data must
be submitted.
The effect of topography on erosion is accounted for by the LS factor, which combines the effects of a hillslope-length
factor, L, and a hillslope-gradient factor, S. Generally speaking, as hillslope length and/or hillslope gradient increase,
soil loss increases. As hillslope length increases, total soil loss and soil loss per unit area increase due to the
progressive accumulation of runoff in the downslope direction. As the hillslope gradient increases, the velocity and
erosivity of runoff increases. Use the LS table located in separate tab of this spreadsheet to determine LS factors.
Estimate the weighted LS for the site prior to construction.
